Nutrition education: Optimising preparation and recovery for benign oesophageal surgery

BACKGROUND

Patients requiring upper gastrointestinal surgery for benign oesophageal conditions are at nutrition risk before and after surgery. There is a dearth of published evidence guiding clinicians on effective collaboration with patients to mitigate perioperative nutritional challenges. We conducted a qualitative study aiming to explore patients' perioperative food, nutrition, and educational experiences to guide future care.

METHODS

Adult patients who had undergone elective, benign oesophageal surgery were invited to participate in semi-structured interviews within 3 weeks of hospital discharge. Interviews were transcribed and analysed with a reflexive form of inductive thematic analysis in addition to synthesised member checking.

RESULTS

Interviews with 12 patients identified three major themes. First, nutrition education fosters a better surgical recovery experience: patients expressed a desire to be prepared for their upcoming surgery and engage in the recovery process with informed food choices. Most patients preferred preoperative education given limited capacity for learning during hospital admission. Second, patients have priorities for nutrition information: patients expressed that educational material should be printed, comprehensive, practical, include familiar foods and focus on managing postoperative physical symptoms. Third, food impacts social and emotional experiences of surgery: resumption of a normal diet was a sign of recovery that enabled social reintegration. Identified themes resonated with Knowles' six-core principles of andragogy.

CONCLUSIONS

Patients with benign oesophageal conditions perceived nutrition education to be a vital aspect of surgical preparation and recovery. Re-designing perioperative education with patient input has the potential to improve outcomes and experiences.

The prevalence of intestinal dysbiosis in patients referred for antireflux surgery

Background

Prior to antireflux surgery, most patients with symptoms of gastroesophageal reflux disease (GERD) have been taking long-term proton pump inhibitors (PPIs). PPIs have been shown to cause changes to the intestinal microbiota, such as small intestinal bacterial overgrowth (SIBO), which is characterised by symptoms of gas bloating. Patients undergoing antireflux surgery are not routinely screened for SIBO, yet many patients experience gas-related symptoms postoperatively.

Methods

Data from consecutive patients (n = 104) referred to a speciality reflux centre were retrospectively assessed. Patients underwent a routine diagnostic workup for GERD including history, endoscopy, oesophageal manometry and 24-h pH-impedance monitoring off PPIs. Intestinal dysbiosis was determined by hydrogen and methane breath testing with a hydrogen-positive result indicative of SIBO and a methane-positive result indicative of intestinal methanogen overgrowth (IMO).

Results

60.6% of patients had intestinal dysbiosis (39.4% had SIBO and 35.6% had IMO). Patients with dysbiosis were more likely to report bloating (74.6% vs 48.8%; P = 0.01) and belching (60.3% vs 34.1%; P = 0.01). The oesophageal acid exposure time and number of reflux episodes were similar between dysbiosis and non-dysbiosis groups, but patients with dysbiosis were more likely to have a positive reflux-symptom association (76.2% vs 31.7%; P < 0.001), especially for regurgitation in those with SIBO (P = 0.01). Hydrogen gas production was significantly greater in patients with a positive reflux-symptom association for regurgitation (228.8 ppm vs 129.1 ppm, P = 0.004) and belching (mean AUC 214.8 ppm vs 135.9 ppm, P = 0.02).

Conclusions

The prevalence of intestinal dysbiosis is high in patients with GERD, and these patients are more likely to report gas-related symptoms prior to antireflux surgery. Independently, SIBO may be a contributory factor to refractory reflux symptoms and gas bloating in antireflux surgery candidates.
